Tom chases Jerry at the harbor. There he falls in love with a kitten and he follows her on a cruise ship to the Caribbean. All the time Jerry tries to break their love. He succeeds in the end, and Tom chases Jerry back into the harbor.

Although Jerry is quite unsympathetic in all Gene Deitch’s Tom & Jerry films, his character is particularly nasty in this one. Unlike a Hanna-Barbera Tom & Jerry like ‘Springtime for Thomas’ (1946), one cannot sympathize with Jerry’s actions, as his reasons remain unclear.
